Carb throttle shaft play (1 Viewer)

[rusty_sherpa]

Currently going through the vacuum lines and carb. I noticed gunky varnished gas at the main throttle shaft. It also has a fair amount of play - approximately 1/32” or a little less than 1 mm. I’m thinking it’s also causing a vacuum leak.

I did a search and found mentions of bushing replacements. Are they still available and by whom?

…to close the loop on the thread. I installed new bushings from a Quadrajet carb repair kit. Requires very minor modifications. Very easy. Worked out great. Snug as a bug in a rug.

Yep. I didn't find much on the topic. Best to post and let others get some info.
